Comment typeDescription
Alternative ProductsEvent=Alternative splicing; Named isoforms=2; Name=1; IsoId=Q9MA55-1; Sequence=Displayed; Name=2; IsoId=Q9MA55-2; Sequence=VSP_037739; Note=Derived from EST data. No experimental confirmation available.;
FunctionBinds medium- and long-chain acyl-CoA esters with very high affinity. Can interact in vitro with oleoyl-CoA, barely with palmitoyl-CoA, but not with arachidonyl-CoA. May function as an intracellular carrier of acyl-CoA esters. Plays a role in the biosynthesis of membrane lipids including galactolipids and phospholipids. {ECO:0000269|PubMed:15604682, ECO:0000269|PubMed:18773301}.
InductionBy 1-aminocyclopropane-1-carboxylic acid (ACC, ethylene precursor), methyl jasmonate (MeJA), and Botrytis cinerea. Up- regulated in the light and down-regulated in constant darkness. {ECO:0000269|PubMed:18836139}.
InteractionP42736:RAP2-3; NbExp=4; IntAct=EBI-2009699, EBI-368243;
SimilarityBelongs to the ACBP family. {ECO:0000305}.
SimilarityContains 1 ACB (acyl-CoA-binding) domain. {ECO:0000255|PROSITE-ProRule:PRU00573}.
SimilarityContains 6 Kelch repeats. {ECO:0000305}.
Subcellular LocationCytoplasm {ECO:0000269|PubMed:18773301, ECO:0000269|PubMed:18836139}. Note=Also to the periphery of the nucleus.
SubunitInteracts with RAP2-3/EBP, an ethylene-responsive element binding protein. {ECO:0000269|PubMed:18836139}.
Tissue SpecificityMostly expressed in roots, stems, and leaves, and, to a lower extent, in flowers and siliques. {ECO:0000269|PubMed:15604682, ECO:0000269|PubMed:18836139}.
